Today I begs for to advise Main Power Amplifier OCL 100watt by MJ802, MJ4502. May pleasing of friends at like firm bass and Treble be bold. Because it is Amplifier OCL model Class AB. And it has electric tall power about 100Watt at 8ohm size loudspeakers. Then can use in the work party or in the system home theater get comfortablely. Important aspect be power supply Source must have enough about +38V GND -39V that Current do not lower 3 Amp per Chanel. When see the circuit has moderately detail. Then not convenient for a novice for the convenience and friends have model PCB give friends see with. Have a good time with sound of sweet-sounding music , please sir.
